Hereinafter, each processing flow in the online education system 100 of this embodiment will be described with reference to the flowcharts of FIGS. 4 to 11. FIG.

4 to 11, the CPU 201 of the lecturer PC 101, the student PC 102, the content management PC 103, the student history management server 104, and the content server 105 executes programs stored in storage means such as the external memory 211. is loaded into the RAM 203 and executed.

FIG. 4 is a diagram showing an example of a flowchart of viewing start processing of the online education system 100 of this embodiment.

In advance, the student PC 102 accepts activation of the browser and connects to the content server 105 . Then, the login screen is displayed to accept input of authentication information (for example, ID "User1234", PW "Passwd4321").

Then, in step S401, the student PC 102 transmits the authentication information from the login screen according to the user's operation (for example, pressing the login button).

At step S402, the contents server 105 receives the authentication request from the student's PC 102 and the accompanying authentication information.

At step S403, the content server 105 determines whether the authentication process is successful. For example, a method of transferring authentication information to an authentication server for authentication, or a student management function of course history management.

If the authentication is successful (step S403: OK), the content server 105 proceeds to step S404. If the authentication is successful, the associated authorization information is also notified. Student identification information is implicitly added to subsequent notifications from the student PC and the content server.

If the authentication fails (step S403: NG), the content server 105 proceeds to step S405.

In step S404, the contents server 105 acquires contents that can be viewed by the student from the contents table 1801 when the authentication process is OK.

Here, the contents table 1801 shown in FIG. 18 will be described.

1801 shown in FIG. 18 is a content table 1801 having a content storage. This is an example of content that can be viewed by the student, which is composed of authorization, content identification information, content name, etc., managed by the content table 1801 . Authorization refers to the authority given to a person. Specifically, a student who has the authorization of authorization Az-1 in the content table 1801 can view the online seminar A01 and the online seminar A02. By doing so, if the online seminar B01 is for general manager training, the online seminar B01 can be used to view the general manager (eg, Az-2). Compliance training is something that can be given authority to each student so that everyone can watch it. Of course, one person can have multiple licenses.

At step S405, the content server 105 sends an authentication error to the student PC 102 that sent the authentication request. An authentication error may be notified by an error code or an error message.

In step S406, the content server 105 causes the student PC 102 that has received the authentication error to continue the authentication process by displaying the login screen again.

In step S407, the content server 105 transmits to the student PC 102 a list of pairs of content names and content identification information. For example, a list of {Conts-A01, online seminar A01} {Conts-A02, online seminar A02} is sent to the PC 102 of the student.

At step S408, student PC 102 receives the list transmitted from content server 105. FIG.

In step S409, student PC 102 displays a list of viewable contents (the list received in step S408) on display 210. FIG.

In step S410, student PC 102 accepts selection of desired content from the viewable content list. Specifically, a click on the content name “online seminar A01” in the content table 1801 is accepted.

At step S411, the student PC 102 transmits the content identification information of the selected content to the content server 105. FIG.

At step S412, the content server 105 receives the content identification information from the student's PC 102. FIG.

In step S413, the content server 105 sends a request to the student history management server 104 to search for the group to which the student who selected the content in step S410 belongs. (pass student identification information)

In step S414, the student history management server 104 acquires a list of set groups from the property of the corresponding content. Specifically, the identification information of the group to which the student belongs is acquired from the student group member table 1802 shown in FIG. After that, the group name is obtained from the student group master table 1803 shown in FIG. 18 using the group identification information as a key.

Here, the student group member table 1802 shown in FIG. 18 and the student group master table 1803 shown in FIG. 18 will be described.

Reference numeral 1802 in FIG. 18 denotes a group member table 1802 that the student history management server 104 has. Group member table 1802 manages group identification information and student identification information.

18 in FIG. 18 is the student group master table 1803 that the student history management server 104 has. The student group master table 1803 manages group identification information and group names.

In step S415, the student history management server 104 transmits a list of groups to which the student belongs (affiliated group list).

In step S416, the content server 105 receives a list of groups to which it belongs (affiliated group list).

In step S417, the content server 105 searches for a user list defined in the content properties of the content from the belonging group list received from the student history management server 104. FIG. If there is a match, take the highest weighted value among them. For example, in this embodiment, in the student group weighting table 1804 shown in FIG. 18, the value 200 with the higher weighting value is taken out of the group identification information Gr-001 and Gr-002.

Here, the student group weighting table 1804 shown in FIG. 18 will be described.

Reference numeral 1804 in FIG. 18 denotes a student group weighting table 1804 that the contents server 105 has. A student group weighting table 1804 manages group identification information and weighting values.

In step S418, the content server 105 transmits the weighting value of the student to the student PC 102. FIG.

At step S419, student PC 102 receives the weighting value. Although the value is limited to the content, this weighting value is also implicitly transmitted when this post-processing action is transmitted to the content server 105 .

In step S420, the content server 105 notifies the student history management server 104 that viewing of the content has started.

In step S421, the student history management server 104 receives the content.

In step S422, the student history management server 104 adds the student's history to the content attendance history table 1805 shown in FIG.

Here, the content attendance history table 1805 shown in FIG. 18 will be described.

Reference numeral 1805 in FIG. 18 denotes a content attendance history table 1805 that the student history management server 104 has. The content attendance history table 1805 manages student identification information, content identification information, update date and time, and status.

At step S423, the content server 105 transmits the content to the student PC 102 and the content management PC 103 asynchronously with the update of the weighting value and viewing history information. Along with the content, the slide ID is also sent when the slide is flipped. When the content is completed, the status of the content attendance history table 1805 (viewing history) is updated to "learning-completed". Step S423 is an application example of the generation means of the present invention, and generates a screen including the content managed by the management means.

In step S424, the content management PC 103 holds the latest slide ID in memory.

At step S425, the content management PC 103 displays the content data. Step S425 is an application example of the display control means of the present invention, and controls to display the screen generated by the generation means.

In step S426, the content management PC 103 determines whether the content has ended.

If the content management PC 103 determines that the content has ended (step S426: YES), the processing ends.

If the content management PC 103 does not determine that the content has ended (step S426: NO), the content management PC 103 proceeds to step S424.

At step S427, student PC 102 holds the latest slide ID in memory.

At step S428, student PC 102 displays the content data.

In step S429, the student PC 102 determines whether the content data has ended.

If the student PC 102 determines that the content has ended (step S429: YES), it ends the process.

If it is not determined that the content has ended (step S429: NO), student PC 102 proceeds to step S427.

Next, range selection processing during viewing will be described with reference to FIG. FIG. 5 is a flow of processing between steps S428 and S429 in FIG.

FIG. 5 is a diagram showing an example of a flowchart of range selection processing during viewing in the embodiment of the present invention. This is a flowchart that is started when the student selects a range 1204 for slide 1201 shown in FIG. By selecting a range of parts that were not understood by the contents of the slides and the explanation along them, the parts are displayed as a heat map on the content management PC 103 viewed by the lecturer.

In step S501, the student's PC 102 selects (drags) an unknown portion on the slide using a mouse or the like. A screen 1201 displayed on the student's PC 102 shown in FIG. 12 is a diagram showing an example of a content displayed on the student's PC 102 in which a range is selected 1204 by the student's operation.

Step S501 is an application example of the receiving means of the present invention, and receives designation of an area in which the user is interested in the area of the content via the screen controlled to be displayed by the display control means. .

In step S502, the student's PC 102 receives the range selection by the student's operation and notifies the content server as action information. For example, student identification information: User1234, content identification information: Conts-A01, slide ID: 1, range: FROM (x1:y1)-To (x2:y2), weighting value: 200).

In step S503, the content server 105 receives action information.

In step S504, the content server 105 saves the data received in step S503 as another data format "action log (range)". This data is the basis for creating a heatmap.

Here, the action log (range) table 1806 shown in FIG. 18 will be described.

Reference numeral 1806 in FIG. 18 denotes an action log (range) table 1806 that the content server 105 has. An action log (range) table 1806 manages student identification information, content identification information, slide IDs, ranges, and weighting values.

In step S505, the content server 105 determines whether weighting value adjustment is necessary. From the calibration range specification 1302 of the heat map weighting related setting screen 1301 shown in FIG. 13, it is determined whether or not the slide that has received the range specification action is the calibration slide. A calibration slide is a page for judging (determining) the user's operation characteristics. People who immediately select a range when they do not understand even a little are trying to adjust the balance with other students by lowering the weighting (degree of emphasis on operations). The assumed range of calibration slides is the first few slides of the content.

If the content server 105 needs to adjust the weighting value (it is a calibration slide) (step S505: YES), the process proceeds to step S506. If the number of actions taken by other students is more than a certain percentage (e.g., more than 50% more than the average during the calibration slide), the weighting value is reduced by a certain number (for example, 10%), and in step S506 the content server 105 decides to take action. A new weighting value is transmitted to the PC 102 of the student who has The absolute values of 50% and 10% have no meaning, and instead of treating students who specify a range of "I don't know" in the same way as an average student, The operation of 1.5 times the number of students is intended to reduce the ratio reflected in the heat map by, for example, 10%. The adjustment judgment is performed with a calibration slide. The weighting value is a value that indicates how heavily the meaning of the range designation is received. If 100 is considered normal, the more than 100, the more serious (=easily reflected in the heat map), and the less than 100, the more overlooked (= less likely to be reflected in the heat map).

If the content server 105 does not require weighting value adjustment (not a calibration slide) (step S505: NO), the process proceeds to step S509.

Here, the heat map weighting related setting screen 1301 shown in FIG. 13 will be described.

The calibration range specification 1302 determines the characteristics of each student's range specification amount in the specified range of slides, and automatically changes the weighting value 1304 . In this range, the weighting value of a student with a large range selection amount is reduced based on the difference in range selection amount of individual students and all simultaneous students. (Lightening the treatment of those who choose carelessly)

Group 1303 is a list of students to whom the same weighting value is applied. For example, this weighting value affects the determination of S514 in FIG. 5, S708 in FIG. 7, and S1108 in FIG. As an assumption, the weighting value 1304 in FIG. 13 is assumed to set a large number for beginners and a small number for experts. In this embodiment, a beginner refers to a student who is unfamiliar with the details of the content being viewed (a person who does not have knowledge of the content). An expert is a student who is familiar with the details of the content being viewed (a person who has knowledge of the content). Assume that the default value of 1304 in FIG. Specifically, when the weighting value 1304 is 200%, the heat map threshold value 1407 in FIG. 14 is 30, the unit 1408 in FIG. , the threshold is exceeded (exceeded). Conversely, if the weighting value is 50%, the heat map threshold 1407 is 30, and the unit 1408 in FIG. By setting this threshold, even if the number of people who specified the same range is small, it will be displayed as a heat map on the screen of the content management PC even if the number of people who specified the same range is small. Since it can be judged at any time, it is possible to explain the stuck part more carefully.

Also, as another example, an expert may set a small number. When the expert specifies a small number, it is determined that many people do not understand the part that the expert does not understand, and a more detailed explanation will be given.

The weighting value 1304 can be set, for example, from 0% to 200%. People who belong to multiple groups will adopt the maximum value. It has the effect of raising the range specification action of the members of the selection group.

In step S506, the content server 105 transmits weighting values.

At step S507, the student PC 102 receives the weighting value, and at step S508, the student PC 102 updates the weighting value.

In step S509, the content server 105 determines whether the student has reached the range selection action upper limit setting 1404 of FIG. 14 on the same slide. This is because it is highly likely that students who frequently perform actions deviate from the purpose of the range selection and just do it casually, so the meaning of the actions of students who adhere to the original purpose This is to prevent a relative decrease in Specifically, taking the above-mentioned action log (range) table 1806 as an example, student identification information: User 1234 is content identification information: Number of rows selected in range at slide ID: 1 in Conts-01=Number of times is 1 Therefore, it is determined that the upper limit has not been reached.

When the action upper limit of the student has been reached (step S509: YES), the content server 105 proceeds to step S501.

Contents server 105 shifts the process to step 510 when the action upper limit of the student has not been reached (step S509: NO).

In step S510, the content server 105 transmits the current action log to the content management PC 103. FIG.

In step S511, the content management PC 103 records the data received in step S510 on the memory.

In step S512, the content management PC 103 updates the heatmap. A heatmap is created by projecting a specified area onto a transparent layer. For example, the coordinates on the layer are checked, and the threshold value of the heat map threshold value setting on the heat map display setting screen indicated by 1401 in FIG. 14 is used for determination. A specific example of threshold determination will be given in the description of FIG. Also, when judging the threshold value, a weighting value is added for each student. Step S512 is an application example in which the generation unit regenerates the screen that allows identification of the area for which the designation is received by the reception unit.

Here, the heat map display setting screen shown in FIG. 14 will be described.

1401 of FIG. 14 is a figure which shows an example of a heat map display setting screen.

"Large" of the range designation action amount 1405 of the heat map threshold setting 1402 should definitely be followed, "medium" should be followed, and "small" should be followed if possible. be. The emphasis color 1406 can be specified by the instructor with a color that is easy for the instructor to understand which color corresponds to which action amount. As shown in the heat map display setting screen 1406, the default value is a general warm color gradation of “heat map”. For example, as an example of warm color gradation, the range designation action amount 1405 "large" is red, the range designation action amount 1405 "medium" is orange, and the range designation action amount 1405 "small" is yellow.

Threshold 1407 allows the instructor to input criteria for judging the amount of action. As shown in the heat map display setting screen 1406, the default value is Large: 75%=3 out of 4 students have doubts. Medium: 50% = More than half of all students have doubts. Small: 25% = indicates that more than 1 out of 4 students have doubts. Also, the unit 1408 can be selected from "people" and "%". In the case of the unit of "people", the number of concurrent students of the content selected by the same range of the content being viewed is counted. For example, when the threshold is "25" and the unit is "people", it is determined that the threshold is exceeded if 25 of the concurrent students select the same range.

Also, if the threshold is "25" and the unit is "%", it does not matter how many students are studying at the same time. It is determined that the threshold has been exceeded.

A heat map display timing setting 1403 specifies when to display the heat map. In real time, the heat map is displayed when the condition of "action amount: small" is met regardless of the setting of the display threshold. When the display threshold value is exceeded, it is displayed according to the setting of the display threshold value when the condition is satisfied. Normally, the heat map is not displayed when the slide is flipped, but when the content is flipped, the heat map is displayed according to the heat map threshold setting. Hide always never show the heatmap (even if the threshold is exceeded)

Range selection action upper limit setting 1404 sets the upper limit number of range selection actions allowed per slide of content per student. For example, if it is 3 times/slide, even if one person selects the range 4 times or more on the slide, the heat map display is not affected. Range selection action capping 1404 is not directly related to weighting, but rather deemphasizes the opinion of those who say they don't know too much.

Now, return to the description of FIG.

In step S513, the content management PC 103 determines heat map display settings.

When the heat map display setting is non-display (step S513: non-display), the content management PC 103 does not perform heat map display processing.

When the heat map display setting is real time (step S513: real time), the content management PC 103 proceeds to the process of step S515.

When the heat map display setting is the display when the threshold is exceeded (step S513: display when the threshold is exceeded), the content management PC 103 proceeds to the process of step S514.

In step S514, the content management PC 103 determines whether the current heat map is in a threshold over state.

If the threshold is exceeded (step S514: YES), the content management PC 103 proceeds to step S515.

If the content management PC 103 does not exceed the threshold value (step S514: NO), the content management PC 103 terminates without performing processing related to heat map display.

In step S515, the content management PC 103 combines the heat map with the content and displays it, as indicated by 1501 in FIG. Step S515 is an application example in which the display control means controls to display the screen regenerated by the generation means.

Here, the heat map display screen shown in FIG. 15 will be described. 1501 of FIG. 15 is a figure which shows an example of a heat map display screen.
